Looking better...but still has a way to go. Might want to check your soil's pH to see it is right for the grass you have. Here we try to stay around a neutral pH of 7.0.
The last place I was at had a starting pH 4.1 so it took some fairly heavy liming in the garden spot. I knew something was when the corn in the first started tasseling at 12 inches. After the Fall application the next Spring the corn made it to over 6 feet. But the lawn took longer as I couldn't apply it as heavily, but after several applications it was up to pH 6 which the grass took off like a weed.
